Hi there! I’m Pierre, here to help you get Dancing Line running smoothly again. To start, could you tell me a bit more about when the app crashes? For example, does it crash immediately when you open it, or does it happen during gameplay? Also, have you noticed any error messages or specific actions that trigger the crash?

Meanwhile, I can suggest some initial steps for you to try on your Android device running version 10:

1. Restart your device: Sometimes, a simple restart clears temporary glitches.
2. Clear cache and data for Dancing Line:
- Go to your device Settings > Apps > Dancing Line.
- Tap on Storage.
- Clear Cache first, then if crashing persists, Clear Data (note this may erase saved progress unless connected to an account).
3. Check for app updates: Open Google Play Store, search for Dancing Line, and make sure it's updated to the latest version.
4. Reinstall the app: Uninstall Dancing Line, then download and install it again from the Play Store. This can fix any corrupted files.
5. Free up device memory: Ensure your device has enough free storage space and RAM, as low resources can cause crashes.

If you’ve already tried any of these, please let me know which ones so I can help with more advanced troubleshooting. Also, is your device connected via Wi-Fi or mobile data when the crash occurs?

Looking forward to your details so we can get Dancing Line up and dancing again!
